Specification of Letters Patent.

Patented May as, 1917.

Application filed June 10, 1916. Serial No. 102,997.

WENOK, a citizen of Great Britain, both re siding at St. Cloud, in the county of Stearns, State of Minnesota, have invented a new and useful Sash-Fastener, of which the following is a specification.

It is one object of the present invention to provide novel means whereby a vertically swinging barrier such as a storm window pivotally or hingedly supported at its upper end, may be held at its lower end away from p a support, such as a window frame, and, at the will of an operator, be locked in closed position with respect to the frame or support.

In the accompanying drawings Figure 1 shows the invention in side elevation, assembled with a window frame and a vertically swinging storm window; I

Fig. 2 shows the structure in top plan and in the position of Fig. l, the storm window having been omitted in Fig. 2, and Figs. 1 and 2 showing the parts as they will appear when the lower end of the storm window is swung outwardly;

Fig; 3 is a rear elevation of the fastener, the parts being in the positions whichthey will assume when the storm window has been swung inwardly into closed position with respect to the window frame or support; and

Fig. 4L is a cross section taken approximately on the line 45- 1- of Fig. 3, parts appearing in elevation.

In the accompanying drawings there is shown a support 1 which may be a window frame. The numeral 2 indicates a vertically swinging barrier, which may be a storm window or a blind, such structure preferably being pivoted at its upper end to the frame or support 1, as those skilled in the art will clearly understand without specific delineation.

Thefastenerpreferably is made of metalthroughout and embodies an inner arm 3 and an outer arm 4-, united by a pivot element 5. On its upper edge, the inner arm 3 is provided with a shoulder 6 which, coacting with the upper edge of the outer arm 4 adjacent the pivot element 5, serves be alluded to hereinafter.

thereof.

to maintain the parts 3 and l in alinenient, *when the barrier 2 is swung outwardly, as shown in Fig. 1. In the inner arm 3 ad jacent its inner end is fashioned an opening 7 which may be denominated a keeper. The inner arm 3 is supplied upon its lower edge directly below the opening 7 with a defleeting lip 8. Attached to the support or window frame 1 is afoot plate 9, and by means of a pivot element 10, the inner end of the arm 3 is held to the foot plate 9 for vertical swinging movement. The foot plate 9 is equipped with a shoulder 25 which will The numeral 11 designates an L-shaped bracket which projects laterally from the outer arm 4 near to the outer extremity Mounted to reciprocate in the bracket 11 and in the outer arm 4 and disposed transversely of the outer arm is a latch 12 preferably in the form of a rod or bar supplied at one end with a handle 14 which may be an eye. The latch 12 is beveled at one end, as shown at 15, so that it may cotiperate with the deflecting lip 8 in a manner which will be set forth hereinafter. The latch 12 carries an abutment which may be a cross-pin 16. Surrounding a portion of the latch 12 is a compression spring 17, one end of which engages the outer portion of the L-shaped bracket 11, the other end of which engages the pin or abutment 16. The spring 17 serves to maintain the beveled end 15 of the latch 12 advanced as shown in Fig. 2. I

The numeral 18 denotes a hanger comprising a base '19 and arectangularly disposed wing 20 carrying a hook-shaped finger piece 24. The base 19 of the hanger is supplied with holes 21 adapted to receive securing ele ments 22 whereby the hanger may be secured to the barrier. 2. A pivoted element 23 unites the outer end of the arm 4 with the wing 20 of the hanger for swinging movement in a vertical plane.

"When the barrier 2 is swung outwardly at its lower end away from the support 1 as depicted in Fig. 1 of the drawings, the outer arm 4 engages the shoulder 6 of the inner arm 3, the parts 3 and 1 thus standing in alinement to serve as a rigid brace efi'ective to maintain the barrier in the position which Fig. 1 discloses. When it is desired to move the barrier 2 to a closed position, the arms 3 and 1 are knuckled upwardly in the direction of the arrow A, the arm 3 swinging on the pivot element 10 of the foot plate 9, and the arm a swinging on the pivot element 23 of the hanger 18. Such an operation, obviously, will permit the barrier 2 to swing to a closed position with respect to the support 1.

WVhen the arms 4 and 3 approach a position of alinement, the beveled end 15 of the latch 12 engages with the inclined deflecting lip 8 of the arm 3. By this operation, the latch 12 is pushed backwardly, until the spring 17 is compressed. Ultimately, the beveled end 15 of the latch arrives opposite to the opening 7, the arms 3 and at by this time being in vertical, upstanding positions.

Then, under the action of the spring 17, the latch 12 is advanced until its beveled end 15 is engaged intheopening or keeper 7. The arms 3 and 4 now are held in alinement and the barrier 2 cannot be moved to an open position.

When the arm 3 arrives in a vertical upstanding position, the rear edge of the arm engagesthe shoulder 25 on the foot plate 9 which is attached to the supportor window frame 1. The arm 3, therefore, is rigidly held against rearward swinging movement.

Copies of this paten'imay be obtained for fiye cents each, by addressing the Having thus described the invention, what is claimed is In a device of? the class described, a frameengaging foot plate having an outstanding shoulder; an inner arm pivoted at one end to the foot plate and provided with an open ing located within the contour of the arm, the arm having a laterally inclined lip disposed adjacent the opening; a barrier-carried hanger; an outer arm pivoted at one end to the hanger and pivoted at its other end to the inner arm; and a spring advanced latch carried by theouter arm and operating transversely thereof, one end of the latch projecting beyond theouter arm; the arms being foldable into alinement and into engagement with the shoulder, the lip serving to engage the projecting end of the latch thereby to retract the latch, as the arms move toward alinement, and the said end of the latch engaging automatically in the opening whenthe arms are in alinement.

In testimony that we claim the foregoing as our own, we have hereto affixed our signatures in the presence of two witnesses.
